The contents on your channel is priceless for true aquarists. You are very talented on teaching and explaining. I have cleared so many questions in my mind with your videos.Thank you
i love your videos! Should have way more views and subscribers for what you are doing. I myself just set up a 29 gallon no water change project tank thanks to you for extra inspiration
Very cool!! Always felt that if you balanced everything you wouldn't need to do water changes. I am very interested in this subject as I am researching for my first marine (salt) aquarium. Thanks for posting a cool experiment!
@Jay First of all thank you very much for these fantastic videos! I learned a lot and you explained it all very easily as well. I got a question though, in your filtration videos you showed how to stack up the media in a filter in the right way, with the most dense media at the bottom, to maximise filtration effects and reduce maintenance. Could this be applied to a deep substrate as well, with gravel at the top and a dense sand bed below? The flow of water to the bottom should be less restricted and the larger surface area of the sand then could create more bacteria or did I got that wrong? Would it be possible to lower the depth of the substrate, with this layered approach and a more dense media at the bottom?
Hi Jay, love your experiments and explanations. Going back to your different depth substrate experiments it would seem that as long as you have at least a 5cm depth of substrate we shouldn’t have any issues with high nitrates yet we do (or at least I do). I have a 30l tank with cat litter substrate (basically baked clay similar to some aqua soils) with no filter which is always zero nitrates as opposed to a 125 L, low stocked tank with filter which is always around 40ppm nitrates even with deep substrate area. I have previously had the same tank with deep substrate area at the back which also produced zero nitrates. I’m wondering if water flow within the tanks is possibly stopping anoxic conditions in some cases? What are your thoughts?
What about just a plain sponge? If I'll put instead of dirt or gravel just a few sheets of sponge one on top of the other, for about 10 centimetres,should it do the trick for removing nitrates out of the water? Sponge is way more light, easy to handle, easy to clean kind of substrate.
Thank you for all your experiments and tutorials. One of the best "aquarium water" teachers on the net.
I will do a very deep substrate for my next tank. Great work.

Thanks Jay. Been following your channel for a while and have learned alot. Very much appreciate your informative content.
love your videos, your channel alone taught me more than I needed to know about aquariums than any other channel has
nice experiment i love that
This is an excellent channel Jay! :)

Clearly the most informative channel there is about aquariums. What's your opinion on the biohome media? Is it worth it? Pretty expensive

sponge is much more expensive to fill the same space. I have not tested sponge for this reason
hey jay, can you please start a experiment a planted tank with ATS(algae turf scrubber) ?
Is sand better than gravel?
Both work well. Not sure which is better
Jay, I see the substrate is black. Why is it black? Is there any soil substrate in it?
Its black pebbles
